/* There are essentially two types of behaviour concerning dot simplification,
* not counting opaque schemes:
*
* 1) Simplify dots if and only if the first element is not a single or double
* dot. If a double dot would rewind past the root, ignore it. For example:
*
* http://hostname/a/../../b/. -> http://hostname/b/
* http://hostname/./../../b/. -> http://hostname/./../../b/.
*
* 2) Effectively treat all paths as relative. Always simplify, except if a
* double dot would rewind past the root, in which case emit it verbatim.
* For example:
*
* wine://hostname/a/../../b/. -> wine://hostname/../b/
* wine://hostname/./../../b/. -> wine://hostname/../b/
*
* For unclear reasons, this behaviour also correlates with whether a final
* slash is always emitted after a single or double dot (e.g. if
* URL_DONT_SIMPLIFY is specified). The former type does not emit a slash; the
* latter does.
